Need some help debugging an issue that only started after upgrading to Monterey. Our application is failing to start resulting in a segmentation fault. I am new to debugging such things on MacOS. Using lldb I get the following back trace. Tells me a little but I am unsure how to approach the issue. Looks like it may be related to loading symbols from a dynamic library? Oh, and yes, everything was rebuilt and all dependent libraries installed / upgraded with brew, etc.

Thanks, Bob

I would need to compile a debuggable version of libmalloc.

Or debug this entirely at the assembly level (-:

Seriously though, compiling libmalloc is not something I’d attempt. In my experience Darwin open source is a super helpful reference but building it is a real challenge.

How can I go deeper?

At this point I’m going to recommend that you open a DTS tech support incident so that I can carve out some time to look at this in more depth.

Does anyone know how to fix this

It’s hard to say what’s going on here because of the formatting on your comment but I strongly suspect that this is unrelated to the issue being discussed on this thread. Note that you’ve crashed with EXC_ARITHMETIC whereas the other posts are all EXC_BAD_ACCESS.

I encourage you to start a new thread for your issue. When doing that:

Include a full copy of your crash report; see Posting a Crash Report for advice on that front.
Add the Debugging tag so that I see it go by.
